Inserting Links causes issues

I hope this makes sense. (I’ve noticed something strange on this forum)

As you will see from my previous message I’ve been having an issue with posting a topic in the “categorization issues” section. (My message kept on getting stuck in moderation?)

Out of frustration I started to post my message in small portions and bit-by-bit it was allowed through.

However when I posted a section and inserted a link using the Insert Link icon (see picture) it didn’t get posted?

But when I posted the same section and just typed the URL (which automatically got turned into a link after posting) the section did get posted?
